  2. Stress–strain curve - Wikipedia

    en.wikipedia.org/wiki/Stressstrain_curve

    The stress and strain can be normal, shear, or a mixture, and can also be uniaxial, biaxial, or multiaxial, and can even change with time. The form of deformation can be compression, stretching, torsion, rotation, and so on. If not mentioned otherwise, stressstrain curve typically refers to the relationship between axial normal stress and ...

  3. Four-point flexural test - Wikipedia

    en.wikipedia.org/wiki/Four-point_flexural_test

    The four-point flexural test provides values for the modulus of elasticity in bending, flexural stress, flexural strain and the flexural stress-strain response of the material. This test is very similar to the three-point bending flexural test .

  4. Three-point flexural test - Wikipedia

    en.wikipedia.org/wiki/Three-point_flexural_test

    The three-point bending flexural test provides values for the modulus of elasticity in bending, flexural stress, flexural strain and the flexural stressstrain response of the material. This test is performed on a universal testing machine (tensile testing machine or tensile tester) with a three-point or four-point bend fixture.

  5. Mohr's circle - Wikipedia

    en.wikipedia.org/wiki/Mohr's_circle

    Mohr's circle for plane stress and plane strain conditions (Pole approach). Any straight line drawn from the pole will intersect the Mohr circle at a point that represents the state of stress on a plane inclined at the same orientation (parallel) in space as that line.

  6. Compressive strength - Wikipedia

    en.wikipedia.org/wiki/Compressive_strength

    As the load increases, the machine records the corresponding deformation, plotting a stress-strain curve that would look similar to the following: True stress-strain curve for a typical specimen. The compressive strength of the material corresponds to the stress at the red point shown on the curve.

  7. Structural material - Wikipedia

    en.wikipedia.org/wiki/Structural_material

    Steel is a ductile material, which will behave elastically until it reaches yield (point 2 on the stressstrain curve), when it becomes plastic and will fail in a ductile manner (large strains, or extensions, before fracture at point 3 on the curve). Steel is equally strong in tension and compression.

  8. Deformation (engineering) - Wikipedia

    en.wikipedia.org/wiki/Deformation_(engineering)

    Depending on the type of material, size and geometry of the object, and the forces applied, various types of deformation may result. The image to the right shows the engineering stress vs. strain diagram for a typical ductile material such as steel.

  9. Flexural modulus - Wikipedia

    en.wikipedia.org/wiki/Flexural_modulus

    In mechanics, the flexural modulus or bending modulus [1] is an intensive property that is computed as the ratio of stress to strain in flexural deformation, or the tendency for a material to resist bending. It is determined from the slope of a stress-strain curve produced by a flexural test (such as the ASTM D790), and uses units of force per ...
